The workshop introduces researchers to the GESIS Panel.dbd Digital Behavioral Data Sample, a new data infrastructure that combines web tracking data<https://www.gesis.org/angebot/studien-planen-und-daten-erheben/erhebung/gesis-web-tracking> (URLs, HTMLs, timestamps) with longitudinal panel survey data (approx. 6 waves per year) and provides researchers in the social sciences with the opportunity to field their own studies. The goal of the workshop is to help participants understand what's possible with these data and how to successfully design studies within the framework of the GESIS Panel.dbd. Participants will: * Learn about the structure and potential of the GESIS Panel.dbd data * Work on their own research ideas with expert input * Get access to an exclusive post-workshop Call for Study Proposals, This workshop is aimed at researchers in the social sciences and related fields.
